Memory Mapped File with zero-size file #54

Current implementation crash when save zero-sized file.

I suggest a new interface for graph writers. We don't specify the types in the writer constructor. When users want to store some kind of data, he calls writer.NewDataFile(type_size, count), which returns some GraphDataStorage type. Then he writes to that stroage, and sets vertex data or edge data to that storage. This is also a step towards heterogeneous graph.

We can also record the type info as a header in this storage.
